| Botanical species |
Species and plant source influence composition, odor, active profile, and commercial value. |
Botanical name, plant part, country of origin, and traceability statement. |
| Chemotype |
Different chemotypes may contain different dominant compounds such as thymol, carvacrol, linalool, or other volatiles. |
Chemotype declaration or GC profile showing the main volatile components. |
| Thymol content |
Thymol is a key marker used to compare many thyme oil specifications. |
Minimum and typical thymol percentage, test method, and COA result. |
| Carvacrol content |
Carvacrol contributes to the product profile and can affect formulation value and aroma. |
Carvacrol percentage and GC profile where available. |
| Total volatile profile |
Minor compounds may influence odor, stability, standardization, and formulation performance. |
GC-MS or GC-FID profile including p-cymene, gamma-terpinene, linalool, borneol, and other relevant compounds. |
| Extraction or production method |
Steam distillation, standardization, blending, and carrier use can change the final specification. |
Production method, standardization approach, solvent statement, and process declaration. |
| Physical form |
Liquid, powder, encapsulated, and carrier-based forms have different dosing and processing behavior. |
Product form, carrier, active load, bulk density, flowability, and dispersion details. |
| Heat stability |
Important for pelleting, extrusion, expansion, and premix processing because volatile compounds can be sensitive to heat. |
Supplier stability data under relevant feed-processing conditions. |
| Odor intensity |
Strong aromatic oils can affect warehouse handling, worker comfort, feed aroma, and cross-contamination risk. |
Odor description, handling guidance, packaging type, and storage recommendation. |
| Carrier or encapsulation matrix |
Carrier selection affects active concentration, label declaration, flowability, and release behavior. |
Carrier type, carrier percentage, feed-grade declaration, allergen status, and GMO statement when required. |
| Contaminant controls |
Needed for feed safety, customer audits, and import approvals. |
Heavy metals, pesticides, residual solvents, microbiology, PAH, dioxin, PCB, mycotoxin, and other required limits. |
| Shelf-life |
Volatile compounds can change during storage, especially if exposed to heat, light, oxygen, or poor packaging. |
Manufacturing date, expiry or retest date, shelf-life, packaging protection, and storage conditions. |
| Regulatory positioning |
Permitted use, additive category, and claim wording may differ by country. |
Feed additive classification, intended use, label wording, registration support, and destination-market compliance documents. |
